Ensuring that employees wear necessary equipment and conduct regular inspections are important measures to reduce accident risks and protect employee safety. However, traditional manual inspections have some problems and cannot meet the needs of modern safety management.
[0003] Traditional manual inspections are prone to omissions and subjective judgment bias. Inspectors need to rely on their naked eyes to judge whether employees are wearing the required equipment, such as glasses, protective clothing, and helmets. This subjective judgment is easily affected by individual experience and emotional factors, and there is a risk of missed inspections and misjudgments, leading to safety hazards. There are problems with equipment wearing detection and inspection personnel supervision in the existing production safety management. Traditional manual inspections cannot accurately judge the equipment wearing status of employees, and cannot monitor the arrival of inspection personnel and the number of inspections in real time, resulting in safety hazards and incomplete management.
[0004] Through the automated equipment wearing detection and inspection supervision system, the accuracy, comprehensiveness and real-time performance can be improved, so as to ensure that each employee wears the necessary equipment and supervise the inspection personnel's attendance and inspection frequency. This can greatly reduce the risk of accidents and improve the effect and level of safety production management. This detection device is fixed on both sides of the channel and cannot be raised or lowered. This leads to poor passage when large-sized items need to pass through and when it is used as a fast channel for people to pass through. Utility Model Content
[0005] In view of the above-mentioned prior art, in order to judge whether the employees are wearing equipment, the detection device installed in the passage will cause obstruction to the passage, resulting in passage being affected. The utility model provides a safety production inspection device. Through this device, the problem that the height of the detection device cannot be adjusted adaptively and it is inconvenient to store it to avoid obstruction to passage can be solved.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a production safety inspection device, comprising columns arranged on both sides of a pedestrian passage, grating components are arranged on the columns, the grating components include grating components A and grating components B, grating component A is installed on the column on one side, grating component B is installed on the column on the other side, grating component A and grating component B are arranged opposite to each other, and also includes a land base, a lifting component is arranged in the column, the column includes a base and a lifting column arranged above the base, the grating component A and grating component B are respectively installed on corresponding lifting columns, the lifting columns can be vertically lifted and lowered in a foundation pit of the land base through the lifting components, and a cover plate component is provided at the foundation pit opening of the foundation pit so as to be openable and closable.
[0007] Furthermore, the lifting assembly includes an electric push rod, the cylinder of which is fixed above the base, the top of which is fixed to the column, the electric push rod drives the column to move vertically back and forth, and controls the height of the column relative to the ground through the stroke of the push rod.
[0008] Furthermore, two guide rods are vertically arranged on the base, and the two guide rods are located inside the lifting column, and the lifting column can reciprocate vertically along the guide rods.
[0009] Furthermore, the cover plate assembly includes a base plate and a cover plate rotatably connected to the base plate, the cover plate can be opened and closed to cover the pit opening of the foundation pit, the bottom of the base plate is connected to an L-shaped support frame, and a hydraulic support rod is arranged between the support frame and the bottom of the cover plate.
[0010] Furthermore, the grating component uses a SICK-MLG series grating module.
[0011] Furthermore, a control circuit connected to the grating component is arranged in the column, a wiring port is arranged on the column, and the grating component is connected to the control circuit in the column by plugging into the wiring port of the column through a data connection line.
[0012] Furthermore, the control circuits in the two columns are connected via a data line, and the data line is pre-buried in the infrastructure between the two columns.
[0013] In summary, the utility model has the following beneficial effects:
[0014] (1) The columns are designed to be liftable, so that the two columns, grating A and grating B can be buried in the foundation pit on the land. When not in use, the columns are stored in the foundation pit and the cover plate covers the opening of the foundation pit.

[0022] The utility model is further described in detail below in conjunction with the embodiments.
[0023] When implementing: Figure 1 and Figure 4As shown, it includes columns 1 arranged on both sides of the pedestrian passage, and grating components are arranged on the columns 1, the grating components include grating parts A2 and grating parts B3, the grating parts A2 are installed on the column 1 on one side, and the grating parts B3 are installed on the column 1 on the other side, and the grating parts A2 and the grating parts B3 are arranged opposite to each other, and the grating components form a detection grating 21 for detecting objects passing through the pedestrian passage between the columns 1 on both sides; an alarm component and a reset button are installed on one side of the columns 1, and the reset button is configured to reset the alarm component after the alarm, and also includes a land base 6, a lifting component is arranged in the column 1, the column 1 includes a base 11 and a lifting column 12 arranged above the base 11, the grating parts A2 and the grating parts B3 are respectively installed on the corresponding lifting columns 12, and the lifting columns 12 can be vertically lifted and lowered in the foundation pit of the land base 6 through the lifting components, and the foundation pit opening of the foundation pit is provided with a cover plate component so as to be openable and closable.
[0024] The current measuring grating is composed of a transmitter and a receiver, while the present device is arranged on two columns 1 relatively by grating member A2 and grating member B3, wherein grating member A2 and grating member B3 form a detection grating 21, and the grating realizes the automatic detection of the equipment wearing condition at the entrance of the personnel aisle. When in use, it is necessary to predetermine the characteristics of each wearing device, such as the characteristic information of glasses, protective clothing and helmets, including their size information, and obtain the size and shape of various safety equipment for predetermination. When a person passes through the detection grating 21, the laser beam is cut off, and the controller can sense this change and detect the person's wearing condition, including the whole body of the person, wherein the spacing between each laser of the grating is 1mm-2.5mm, so as to be able to detect smaller objects including goggles.
[0025] In the specific implementation, the grating component uses the SICK-MLG series grating module. The control circuit connected to the grating component is set in the column 1, and the column 1 is provided with a wiring port. The grating component is connected to the control circuit in the column 1 by plugging into the wiring port of the column 1 through a data connection line. The control circuits in the two columns 1 are connected through a data line, and the data line is pre-buried in the infrastructure between the two columns 1. The control circuit is an existing circuit structure, which is compatible with the SICK-MLG series grating module.
[0026] During implementation, the column 1 includes a base 11 and a lifting column 12 disposed above the base 11 and capable of vertical movement. The lifting assembly includes an electric push rod 4, a cylinder 41 of which is fixed above the base 11, and a top end of a push rod 42 of which is fixed to the column 1. The electric push rod 4 drives the column 1 to move back and forth vertically, and controls the height of the column 1 relative to the ground through the stroke of the push rod 42. Two guide rods 5 are vertically disposed on the base 11, and the two guide rods 5 are located inside the lifting column 12. The lifting column 12 can move back and forth vertically along the guide rods 5. The electric push rod 4 is a prior art. The grating component A2 and the grating component B3 are disposed on the lifting column 12. The cylinder 41 and the guide rod 5 are both arranged inside the column 1 and are fixedly connected to the base 11. The base 11 is fixedly arranged at the bottom of the foundation pit. The base 11 is used to install the driving motor in the electric push rod 4 device. The driving motor is connected to the push rod 42 in transmission, so that the push rod 42 drives the lifting column 12 to move vertically, and the detection grating 21 covers the position from the human feet to the head.
[0027] During implementation, the cover plate 71 assembly includes a base plate 7 and a cover plate 71 rotatably connected to the base plate 7. The cover plate 71 can be opened and closed to cover the pit opening of the foundation pit. The bottom of the base plate 7 is connected to an L-shaped support frame 8, and a hydraulic support rod 9 is provided between the support frame 8 and the bottom of the cover plate 71. When not in use or when a transport vehicle or other items need to pass through, the detection grating 21 can be lowered. At this time, the column 1 needs to be covered at the pit opening. Therefore, the base plate 7 is rotatably connected to the base plate 7 by one side of the cover plate 71, and the hydraulic support rod 9 is connected between the bottom of the cover plate 71 and the support frame 8. In this way, the pit opening can be easily covered, and while protecting the detection device, the land base 6 is made flat for pedestrians to pass through.
[0028] In addition, in the specific implementation, a tag reading module can be set to further assist in identifying the identification card worn by the personnel, wherein the tag reading module performs detection within a predetermined time to monitor the inspection and supervision of the inspection personnel within the predetermined time range. In the personnel identification scenario, the identification card carried by the personnel usually contains a unique identifier or identity information. The tag reading module can read the information on the identification card and transmit it to the controller, which can use this information to verify the identity of the person. As an implementation method, for example, RFID (radio frequency identification) tags or barcodes, and identification methods such as NFC can be used.
[0029] During operation: an infrared grating is formed between the two columns 1. By using infrared light as the light source of the grating element, the stability and sensitivity of the device can be improved. The infrared grating has high precision, non-contact, high efficiency, and less interference in the environment, which can reduce the possibility of misjudgment and missed detection, so as to more reliably detect the equipment wearing of personnel. In the SICK-MLG series grating module, the controller is connected to the grating element A2 and the grating element B3 by electrical signals, which is used to determine whether an object has entered the detection grating 21 and output the result signal of the outline size of the object passing through. By connecting the controller with the grating element A2 and the grating element B3 by electrical signals, it is possible to determine whether an object has entered the grating. When the grating is cut off, the controller can sense the entry of the object, and output the corresponding signal according to the result of the outline size judgment of the object passing through, and match it with the predetermined input information to determine whether the wearing meets the safety requirements. In this way, it can accurately determine whether the personnel are wearing the necessary equipment, providing a reliable basis for subsequent inspection management. The alarm 3 selectively issues an alarm based on the judgment result signal issued by the controller. The alarm can issue an alarm through a human-perceivable signal so as to promptly remind the inspection personnel or other relevant personnel to pay attention to the existing safety problems. In this way, improper equipment wearing or other safety hazards can be quickly responded and resolved, thereby improving the timeliness and effectiveness of safety production management.
[0030] When the detection grating 21 of grating element A2 and grating element B3 is cut off within a preset time interval, the controller determines that an object has passed through the grating, and after obtaining the outline size of the object and the identification of the identification card, the controller is used to record the number of cuts, and at this time the controller controls the alarm not to sound an alarm. When the detection grating 21 is cut off within a preset time interval, the device can determine that an object has passed through the grating, and verify the outline size of the object and the identification of the identification card. If the outline size of the object and the identification of the identification card meet the requirements, the controller will record the number of cuts without triggering the alarm to sound an alarm. This can avoid frequent alarm triggering during normal inspection work.
[0031] During implementation, in a non-preset time interval, when the detection grating 21 is cut off, the controller determines that an object has passed through the grating, and obtains the outline size of the object passing through. At this time, the controller controls the alarm not to sound an alarm. In a non-preset time interval, when the detection grating 21 is cut off, the device can determine that an object has passed through the grating, and verify the outline size of the object passing through. If the outline size of the object passing through meets the requirements, the controller will not trigger the alarm to sound an alarm.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
